该函数用来计算时间序列的最大Lyapunov 指数--Wolf 方法(The function used to calculate the time series of the largest Lyapunov index- Wolf Ways)

说明：  随机共振分析弱信号，带MATLAB源码，值得参考(Stochastic resonance weak signal analysis, take the source code, is worth reference)

上传Matlab源代码程序，希望对下载的人有所帮助(Upload Matlab source code procedures in the hope that the right people download help)

In statistics, an expectation-maximization (EM) algorithm is a method for finding maximum likelihood or maximum a posteriori (MAP) estimates of parameters in statistical models, where the model depends on unobserved latent variables. EM is an iterative method which alternates between performing an expectation (E) step, which computes the expectation of the log-likelihood evaluated using the current estimate for the latent variables, and a maximization (M) step, which computes parameters maximizing the expected log-likelihood found on the E step. These parameter-estimates are then used to determine the distribution of the latent variables in the next E step.

设模拟带通信号频率范围1KHz—1.1KHz，设计一个采样频率8KHz数字频谱分析系统，要求频率分辨率0.1Hz。若对信号直接用FFT进行频谱分析(simulation based communications, with the frequency range 1KHz- 1.1KHz. Design of an 8 KHz sampling frequency digital spectrum analysis system requirements frequency resolution 0.1 Hz. If the signal directly FFT spectrum analysis)

使用matlab语言编程解决线性规划的问题(Matlab programming to solve linear programming problems)

电机控制系统，02年开始积累，效果好，速度快，PI控制，经典控制，fuzzy PID，自适应控制，速度位置控制等等，欢迎大家参考。(Servo motor control system, in 2002 began to accumulate, effective, fast, PI control, classical control, fuzzy PID, adaptive control, speed position control, etc., we welcome the reference.)

EEGLAB 中文帮助文档，很有用的， 有需要的同学可以下载下来看看(EEGLAB Chinese help documentation, very useful, there is a need for students to be able to download it and see)

code to find different FFTs.

这是自己写的实现哈夫曼编码的几个MATLAB程序，可以直接运行(This is the realization of their own to write several MATLAB programs Huffman coding, can run)
